A single ratio that answers the only question an operator or investor really has in a tight capital market: are you spending efficiently to grow, or are you lighting cash on fire to post a growth number?
Burn multiple is net burn divided by net new ARR over the same period. It measures how many dollars a company spends to generate one dollar of new recurring revenue. Coined by David Sacks of Craft Ventures, the metric became the dominant efficiency score in the post zero-interest-rate era because it captures growth and burn in a single number. Under one is great, three or more is a problem.
Six things to know about burn multiple before you quote one on a board slide, and why this single ratio quietly replaced three different efficiency metrics after the capital market reset.
Burn multiple is the dollars of cash a company burns to produce one dollar of net new annual recurring revenue in the same window. If a company burned four million dollars last quarter and added two million dollars of net new ARR, the burn multiple is two. The lower the number, the more efficiently growth is being bought.
David Sacks of Craft Ventures introduced burn multiple as a single ratio to replace the three metrics operators were juggling: growth rate, burn, and efficiency. He wanted one number that could sit on the top of a board deck and tell the honest story without a dozen footnotes. The industry adopted it almost overnight.
The widely cited bands are under one is amazing, one to two is good, two to three is cautious, and three or more is a problem. The scale is intuitive: at a burn multiple of one, a company spends a dollar to make a dollar of new ARR; at three, it is spending three dollars to buy one dollar of new ARR, which rarely survives a down market.
During the zero-interest-rate period, growth at any cost worked because capital was effectively free. When rates rose and the market punished unprofitable growth, burn multiple became the metric that separated real businesses from subsidized ones. A company with a burn multiple of five was celebrated in 2021 and uninvestable in 2023.
Growth rate alone rewards burning cash to post a number. Burn alone rewards cutting growth to look efficient. Burn multiple forces both into the same ratio, so neither side can be gamed without the other getting worse. That is why it ended up on the first page of nearly every SaaS board deck after 2022.
The denominator comes from the CRM: new logos, expansion, contraction, and churn roll up into net new ARR. The numerator comes from finance: cash in and cash out across the period net to burn. The two systems have to agree on timing and definition, or the ratio ends up measuring two different quarters stapled together.
Burn multiple is one of the simplest ratios in SaaS and one of the easiest to compute wrong. The arithmetic is a single line. The accuracy depends on getting net burn and net new ARR to describe the same period, measured the same way, with the same definition of what counts. Teams who skip that discipline produce a number that is defensible on paper and misleading in practice.
Pick a period, usually a quarter. Take net burn for the period, meaning cash out minus cash in, excluding financing activity. Take net new ARR for the same period, meaning new ARR plus expansion minus contraction minus churn. Divide burn by net new ARR. The result is the burn multiple for that period.
Net burn is the real cash leaving the business, not an accounting proxy. It is operating expenses plus capex minus revenue collected, over the same window. Financing rounds and debt draws do not count, because the point is to measure how fast the operating business consumes cash, not how much runway the balance sheet has.
Net new ARR is the change in annualized recurring revenue between the start and end of the period. It includes new logos, expansion from existing customers, and reductions from contraction and churn. The number can be negative if a bad churn quarter overwhelms the sales motion, which drives the burn multiple past three and often into undefined territory.
The most common error is a mismatched window. Annual burn divided by quarterly ARR gain, or quarterly burn divided by trailing twelve month ARR, both produce numbers that look clean and lie. The honest version uses the same window on both sides. Quarterly is the industry convention because it is short enough to catch trends and long enough to average out one-off events.
If net new ARR is zero or negative, the burn multiple becomes undefined or negative, which is the metric telling the truth. A company burning cash while shrinking is not operating on a scale from one to three. It is burning fuel to go backward. Teams usually report the raw numbers in this case rather than a nonsensical ratio.
One quarter of burn multiple can be distorted by a lumpy enterprise close or a seasonal pattern. A trailing four quarter burn multiple averages the ratio across the year, which is the version a board usually wants to see alongside the current quarter. The pair catches both the trend and the latest data point.
The reason burn multiple travels so well is that the scale is intuitive. A single digit tells you where the business sits on the efficiency spectrum without needing a chart or a comparison set. The published bands are approximate, not laws of physics, but the market calibrated to them within about eighteen months of the metric being introduced.
A burn multiple under one means the business adds more new ARR than it burns cash. At any real scale, this is extraordinary. It usually indicates product-led growth with strong net retention, high gross margins, and a disciplined cost base. Companies in this band often raise on their own terms, if they raise at all.
A burn multiple between one and two is the healthy zone for most growing SaaS companies. It means the business is spending a reasonable amount of capital to add new ARR and would survive a tighter funding environment. This is the band investors reward with on-strategy term sheets and growth capital.
Two to three signals that growth is costing more than it should. The business is not yet in distress, but it is operating in a band where a market reset or a bad churn quarter can quickly tip it into trouble. Boards usually ask for a path back under two within two to three quarters.
A burn multiple above three means the company is spending three or more dollars to produce one dollar of net new ARR. In a cheap-capital market this was tolerable; in a tight one it is a red flag that drives funding rounds to down-rounds or forced cost cuts. Most companies in this band restructure within a year.
A seed or Series A company with ten customers and a product in flux will often have a burn multiple above three for a quarter or two, because the ARR denominator is small. The bands apply most strictly from Series B onward, when the business should have found its motion and the ratio becomes a measure of unit economics.
A burn multiple falling from four to two over three quarters is a stronger signal than a flat two. The direction tells you whether the business is becoming more or less capital efficient, which is what forward-looking investors underwrite. Boards usually track both the current ratio and the trailing slope.
Burn multiple was published in 2020. It became the dominant SaaS efficiency metric between 2022 and 2024, when the market reset the price of capital. The reason is simple: when money is free, growth at any cost works. When money is expensive, every dollar burned has to produce a return, and burn multiple is the ratio that measures the return directly.
From roughly 2015 to 2021, cheap capital rewarded growth above all else. Teams were valued on revenue multiples and growth rates, with burn treated as a line item on a slide at the back of the deck. Burn multiple existed but did not drive decisions, because capital would be there to cover almost any ratio.
When interest rates rose and public SaaS multiples compressed, private valuations followed. Growth at any cost stopped being rewarded. The market needed a single ratio that captured both growth and efficiency, and burn multiple fit the slot because it had already been circulating in operator and VC circles for two years.
Rule of 40, the previous favorite, added growth rate to profit margin and rewarded a sum above forty. It worked but could be gamed by trading one lever for the other at inefficient ratios. Burn multiple forced the trade into a direct ratio, which closed the gaming surface and made the metric harder to spin.
Within eighteen months of the market reset, burn multiple had moved from footnote to opening slide in most SaaS board decks. CFOs started reporting trailing four quarter burn multiple alongside ARR as the headline operating metric. Boards started asking about it before growth rate.
By 2023, growth-stage term sheets commonly included burn multiple thresholds as covenants or diligence filters. Series B and C rounds often required a burn multiple under two to proceed. The metric moved from board-level reporting into deal structure, which locked in its position as a standard.
Burn multiple is now used inside operating teams, not only in the boardroom. Quarterly plans model it directly. Hiring decisions and marketing budgets are tested against the implied ratio. The question "what does this spend do to our burn multiple" has replaced "what does this spend do to our growth rate" in many planning conversations.
The reason burn multiple survived the shift to tighter capital is that neither side of the equation can be optimized at the expense of the other without the ratio getting worse. A company cannot grow its way out and cannot cut its way out. It has to do both at the same time, which is what a sustainable business actually looks like.
Reporting growth rate alone rewards whatever produces the biggest ARR number regardless of the cash it took to buy. Teams rightly chase the metric they are measured on, which produced a decade of companies with impressive growth and no path to sustainability. Burn multiple ends the trade by putting burn on the other side of the ratio.
Reporting burn alone rewards cutting cost until the number looks small, even if growth stops along with it. A company burning two million per quarter and adding no ARR looks lean on a burn chart and is dying on a business chart. Burn multiple catches that because the ratio balloons the moment growth stalls.
LTV to CAC measures acquisition efficiency per customer, which is useful and narrower. It ignores R and D, G and A, overhead, and the entire fixed cost base of running the company. Burn multiple captures the whole operating envelope, which is why boards use it as the top-level efficiency score and LTV to CAC as a diagnostic underneath.
Rule of 40 adds growth rate to profit margin. A company with sixty percent growth and negative twenty percent margin passes. So does one with twenty percent growth and twenty percent margin. The two businesses are not equivalent on cash efficiency, which Rule of 40 cannot distinguish. Burn multiple draws the distinction directly.
CAC payback measures how many months a new customer takes to repay acquisition cost. It is a cash efficiency metric for one slice of the business. Burn multiple is the all-in version that catches CAC payback plus the fixed costs around it. The two complement each other and answer different questions.
The metric that lands on page one of a board deck has to pass a brutal filter: it has to be hard to game, intuitive to read, and complete enough to tell the real story. Burn multiple is the SaaS metric that currently passes all three, which is why it displaced the alternatives after 2022.
Burn multiple is calculated by finance, but the denominator comes from the CRM. Net new ARR is the sum of new logos, expansion, contraction, and churn, and all four signals live in the system where deals are closed and customer accounts are managed. Without clean CRM data behind the ARR number, the ratio inherits whatever noise the pipeline is carrying.
The CRM tags every closed-won deal as new business or expansion. The sum of new business ARR in the period is the first component of net new ARR. Without that tag, finance ends up building the number by hand, with the usual errors that come from reconciling pipeline reports to accounting reports after the fact.
Expansion ARR comes from existing customers buying more. The CRM tracks it as expansion opportunities tied to the parent account, closed in the period. The pipeline for expansion is often different from the pipeline for new business, with different owners and different stages, and the CRM is where the two reconcile.
Contraction is a customer reducing their contract without canceling. Seat reductions, plan downgrades, module removals. The CRM records the contract change on the account and lowers the account ARR, which rolls up into the net new ARR calculation. A quarter heavy on contraction can quietly ruin the burn multiple.
Churn is a customer canceling entirely. The CRM marks the account as churned and the ARR drops to zero on the renewal date. Churn is the single most powerful variable in burn multiple because it directly subtracts from the denominator, which raises the ratio with no change on the spend side.
The ratio only works when the ARR events are dated to the same window as the burn. The CRM has to record not just the opportunity close date but the contract start, change, and end dates on the account, so finance can roll the ARR movements into the correct quarter without inherited drift.
Strkr tags every deal as new, expansion, contraction, or churn, carries contract dates on every account, and rolls the four categories into a native ARR waterfall for the period. Finance pulls the net new ARR number straight from the CRM, lines it up against net burn, and the burn multiple is calculated without a side spreadsheet in the middle.

A burn multiple under one is amazing and rare, one to two is the healthy target zone for most growing SaaS companies, two to three is cautious and usually requires a plan to improve, and three or more is a red flag in a tight capital market. The bands are directional, not absolute, and early-stage companies with small ARR denominators get grace for a quarter or two.
Burn multiple equals net burn divided by net new ARR over the same period, usually a quarter. Net burn is cash out minus cash in, excluding financing activity. Net new ARR is new ARR plus expansion ARR minus contraction minus churn. The window must be the same on both sides. Quarterly is the industry convention, with a trailing four-quarter average reported alongside.
David Sacks of Craft Ventures coined and published burn multiple in 2020. He introduced it as a single ratio to replace the three metrics operators were juggling at the time: growth rate, burn, and efficiency. The industry adopted it quickly, and by 2022 it had become the standard SaaS efficiency metric on board decks and in VC term sheets.
Net burn is a cash number: how many dollars the business consumed in a period after subtracting cash collected. Burn multiple is a ratio: net burn divided by net new ARR in the same period. Net burn tells you how fast the company is spending; burn multiple tells you how efficiently each burned dollar is producing new recurring revenue.
The capital market reset in 2022 ended the era of free money and growth at any cost. The market needed a single ratio that captured both growth and efficiency without being easy to game. Burn multiple fit the slot because growth and burn sit on opposite sides of the ratio, so neither side can be optimized at the expense of the other without the number getting worse.
Rule of 40 adds growth rate to profit margin and rewards a sum above forty. Burn multiple divides burn by net new ARR, forcing the trade into a direct ratio. A company can pass Rule of 40 at very different levels of cash efficiency, which Rule of 40 cannot distinguish. Burn multiple draws the distinction directly, which is why it displaced Rule of 40 as the headline efficiency score.
Quarterly, with a trailing four-quarter average reported alongside the current quarter. Monthly is too noisy because one lumpy enterprise close distorts the ratio. Annual is too slow to catch deterioration before a bad quarter compounds. Quarterly with a trailing average catches both the trend and the latest data point, which is what boards and investors expect to see.
A CRM feeds the net new ARR denominator. Every deal tagged as new, expansion, contraction, or churn rolls up into the ARR waterfall for the period, which finance divides into net burn to get the burn multiple. Without clean CRM data behind the ARR number, the ratio inherits pipeline noise and ends up measuring two different quarters stapled together instead of one real one.
